Flu vaccine rekindles debate over connection to autism

Canada's chief public health officer, Dr. David Butler-Jones, has repeatedly said that vaccines have a long history of being safe and effective. Weighing in on the autism debate, he noted in a recent interview with Canwest News Service that vaccines are given to children at around the same age as when neurological disorders can surface.

"You can have a close time frame," he said. "Just because something's associated in time does not mean it's causal."

Butler-Jones said he recognizes that parents are searching for answers about autism's cause, but added claims that vaccines are the culprit have not been proven.

"The studies have been pretty clear and consistent that vaccination is not the cause of many of the things that have been claimed around the vaccine," he said.

The benefits of immunization far outweigh the risks, said Butler-Jones, but he understands people need to think carefully about it.

"It's important that they get the facts — not the theory, not the conjecture, not the claims — but the actual facts about what we know about the vaccine and the disease and I think . . . virtually everybody would choose the vaccine," he said.
